The perfect control of your sound.
The 8MB400 mid-bass transducer has been developed in response to a specific market requirement for an 8 ″ inch (200 mm) mid-bass driver that combines excellent linearity with good efficiency and power handling capabilities. It is primarily designed for use as a mid-bass driver in compact 2-way reflex cabinets with a 1 ″ compression driver or tweeter, but as a result of its versatile features, it can also be used in multi-way systems. The curvilinear treated paper cone is formed using a unique wood pulp composition designed to achieve the best possible stiffness. This is done using a polycotton multiroll wrap to provide a greater excursion while controlling the separation modes. The 2 ″ inch (50mm) aluminum wire voice coil employs the same Interleaved Sandwich (ISV) coil technology. It is comprised of a high-strength fiberglass winder that is wound on the inner and outer surfaces to achieve a mass-balanced coil. This results in an extremely linear motor assembly which, together with the highly advanced design of the magnetic structure, provides a high force factor or BL. The voice coil is cooled by incorporating airways between the chassis back plate and the magnetic top plate to channel hot air away from the voice coil and separate and dissipate it. Internal FEA / CAD facilities have been used to optimize flux density and BL factor within the air gap. With the increasing use of sound systems at outdoor events, the 8MB400 loudspeaker's ability to operate in humid environments is a key feature. This has been achieved through a unique cone treatment that makes the cone moisture resistant.
